Weight is defined as the force on an object due to gravity, while mass is the property of a body to resist acceleration by a force. In normal use, we tend to use the units for mass to express weight. The international standard SI unit for mass is based on grams (g). One kilogram is 1,000 grams. One ton is 1,000 kilograms. In the United States, people often use the pound as well. One pound is about 0.45 kilograms.
